Product Number: 13922N
The WAI 13922N is a brand-new 12V 120A alternator. It is built to replace Bosch original-equipment units — including Bosch 0 124 515 028 and 0 124 515 040 — as well as equivalent Valeo and Letrika (Iskra) units across a broad range of Audi, Volkswagen, and Skoda applications. With 140 applications in total, this is a high-demand replacement covering vehicles such as the Audi A4 (B5 and B6 platforms) in 2.4, 2.8, 3.0 and 2.5 TDI variants, spanning model years from the mid-1990s through to the mid-2000s.
The IR/IF design (internally regulated, internally fan-cooled) keeps the unit compact and service-free, eliminating external regulator wiring and reducing installation complexity. Clockwise rotation and an S6 pulley are specified to match the original drive configuration, so the unit drops in without modification. Lester references 13922 and 22987 allow cross-checking against trade catalogues and vehicle application databases.
Manufactured to Bosch OE specification and supplied brand new — not remanufactured — the 13922N delivers the full rated 120A output from the outset, with no core charge and no uncertainty about previous service history.

A. The WAI 13922N is a direct replacement for Bosch original-equipment alternators — specifically Bosch 0 124 515 028 and Bosch 0 124 515 040. It also cross-references to Valeo SG12B025 and Valeo SG12B054, and to Letrika (Iskra) 11.203.459 and 11.203.459 11.204.162. In total there are 6 OE cross-references on this part. To confirm the exact number fitted to your vehicle, search our cross-referenced catalogue by OEM number or ask Simon.
A. This alternator fits Audi, Volkswagen, and Skoda models — 140 applications in total. Audi accounts for the majority of fitments, with coverage spanning the A4 B5 (including 2.8, 2.5 TDI, 2.4, and S4 quattro variants) and A4 B6 (2.4 and 3.0 variants), among many others. Use the selection widget to match your exact make, model, and engine code, or search our cross-referenced catalogue by OEM number. Every fitment shown is backed by our Fit Guarantee.
A. The WAI 13922N is supplied brand new — it is not a remanufactured or reconditioned unit. There is no core charge, and the full rated 120A output is available from installation.
A. The 13922N is a 12V, 120A alternator with clockwise (CW) rotation and an IR/IF (internally regulated, internally fan-cooled) design. It is fitted with an S6 pulley. Lester catalogue references are 13922 and 22987. The manufacturer is listed as Bosch.
A. IR/IF stands for internally regulated and internally fan-cooled. Internal regulation means there is no separate external regulator to wire in — the voltage regulator is built into the unit. Internal fan cooling means the alternator manages its own thermal regulation without requiring external ducting. The result is a straightforward swap that matches the original installation without additional components.
